Filter device



FIG. 1 is a perspective view of the filter device showing my new design;

FIG. 2 is an exploded perspective view shown from the opposite side of FIG. 1;

FIG. 3 is a perspective view of a first internal component thereof;

FIG. 4 is an opposite perspective view of the first internal component of FIG. 3;

FIG. 5 is a perspective view of a second internal component thereof;

FIG. 6 is an opposite perspective view of the second internal component of FIG. 5; and,

FIG. 7 is a perspective view of a third internal component thereof.

The filter device basically comprises two separable housing portions surrounding disc-shaped filter material held within the housing by the internal components. 

I claim the ornamental design of a filter device, as shown and described.
